两个微胚乳超高油玉米群体粒重和含油率对混合选择的选择响应
Selection response to mass selection for kernel weight and oil content in two micro- endosperm super high oil maize populations
摘要
Abstract
The 5 kernel weight, oil content and oil weight of 5 kernels were measured for two micro - endosperm super high oil maize populations by mass selection after 4 cycles in two years, and the selection responses were studied. Result showed that there were significant ( P < 0.01) differences on 5 kernel weight, oil content and oil weight of 5 kernels among cycle populations. The 5 kernel weight was the highest in C4 in two populations, the selection response of the 5 kernel weight was 0. 048g in yellow population C4y, increased by 12. 18% compared with Coy; the selection response of the 5 kernel weight was 0.044g in white population C4w, increased by 10.16% compared with Cow. The oil content was the highest in C3 in two populations, the selection response of the oil content was 3.16% in yellow population C3y, increased by 11.89% compared with Coy the selection response of the oil content was 1. 12% in white population C3w, increased by 4.03% compared with C0w. The oil weight of 5 kernels was the highest in C4 in two populations, the selection response of the oil weight of 5 kernels was 0.022 1g in yellow population C4y, increased by 21.25% compared with Coy; the selection response of the oil weight of 5 kernels was 0.016 lg in white population C4w, increased by 13. 39% compared with Cow,. The 5 kernel weight, oil content and oil weight of 5 kernels were increased significantly in two populations after 4 cycles mass selection. Mass selection in early generation populations was effective in improving these traits in micro - endosperm maize.关键词
